一文看懂荣耀MagicBook Pro 16
荣耀猎人回归！七大亮点看懂不只是轻薄本，更是游戏本的MagicBook Pro 16.
人们对于笔记本电脑有一个固有印象：要么轻薄但性能一般，要么性能强劲但笨重臃肿。然而，今年荣耀新推出的MagicBook Pro 16刷新了人们的认知——发布会上，荣耀宣布猎人游戏本正式回归，称其继承了荣耀 HUNTER 基因，并自信地为其打出“轻薄本，更是游戏本”的口号。
众所周知，寻求轻薄本的用户普遍更看重便携性、外观造型、静谧性和打字办公等用机体验，而寻求游戏本的用户则普遍更看重硬件配置、性能释放等硬核指标。把两个看似难以相干的产品融合到一起，我们不禁对它产生了强烈的好奇：作为代表荣耀猎人游戏本的跨界新物种，它究竟做了哪些平衡以兼顾不同人群的各类需求呢？
